| 摘 要： | 采用矢通量分裂法求解2D-Euler方程组, 对亚燃/超燃双重燃烧冲压发动机(DCR)进气分流流场及其双重燃烧的冷态掺混流场进行了数值模拟。计算结果给出了全流场清晰的激波结构, 并提供了超燃室中两股高速气流掺混的物理图像。本文的数值结果对于亚燃/超燃双重燃烧室的点火燃烧研究提供了一些有用的信息。

| Abstract: | The flux vector splitting method is adopted to solve the 2-D Euler equations and a numerical simulation is conducted for the division-flow inlet of Dual Combustor Ramjet (DCR) as well as the cold-mixing flow field of both flows from a dump combustor and from a supersonic inlet.The computational results provide a clear shock construction of the whole flow field and physical pictures of the two mixing high-speed streams in the supersonic combustor.The numerical results of the research can be available for reference to the ignition and combustion of the DCR. |
